I'd say our defence is also better just because of continuity, which is why I place your mid slightly better. Our defenders have been playing together for 6 years now. They know each other perfectly. And when you add in depth like Benatia and Rugani, I just don't think it's that close.
Your mid has more continuity than ours, even if it also has those same injury woes as we have. Our midfield 3 of Khedira-Marchisio-Pjanic has actually played something like 4000 minutes more than Vidal-Martinez-Thiago over the last 2 years. But Marchisio is out with an ACL right now, and Pjanic hasn't played a match yet, add in Asamoah who hasn't played in midfield in several years.
Your attack = Our attack in quality.... However, when you add in that continuity factor again, I'd say yours is a wee bit better until we see how Higuain-Dybala mesh.
